A critical analysis of Power Quality issues in Data Center

Data Center in electrical power system is used to record and store all the activities in the power system network. Data center have the Information Technological (IT) equipment Power Supply Unit (PSU) to process the power system data. Uninterrupted power supply (UPS) unit required for powering IT equipment PSU. IT equipment PSU and UPS absorbs more reactive current and inject harmonic current into the power system network. This paper analyses the Power Quality issues of IT equipment PSU and UPS used in the Data Center. This paper also give a suggestion for mitigation of harmonics present in the data Center.
